摘要:
The present invention provides an intake manifold that improves the intake performance and has a reduced weight. The intake manifold includes a surge tank and intake pipes. Each intake pipe has an inlet port that is connected to the surge tank. The inlet ports are arranged along a flow direction of air drawn into the surge tank from the opening of the surge tank, and project into the surge tank along direction that intersects the flow direction. Each adjacent pair of the inlet ports are separated only by a single common pipe wall.

A wireless resource allocation control system for allocating and releasing wireless resource used for communication between vehicles in a predetermined area is provided. The control system includes a unit mounted on a vehicle, and the unit includes a transmitter for transmitting first information associated with the vehicle. A station receives information from the unit and sends information to the unit. The station calculates a priority level for each of the units on the basis of the first information transmitted from each of the units, ranks the units in the order of the priority level, allocates wireless resources to the units in descending of the priority levels, and releases the wireless resource previously allocated to the unit in the case of the unit unworthy of current allocation of the wireless resource.

A filter element for an air cleaner including a sheet-like filter medium for purifying air when the air is transferred from one side to the other side of the filter medium, a frame member having a flange confining the filter medium and a side wall formed on the flange, and a fibrous mat having cushioning effect. The filter medium is folded in a sawtooth-shaped pattern and extends along a plane. The filter medium has a base contour contained in the plane and has a sawtooth-shaped peripheral edge section extending along a part of the base contour. The flange outwardly projects from the frame. The side wall is airtightly bonded to the sawtooth-shaped peripheral edge section of the filter medium. The mat continuously extends along the base contour and is fixedly bonded to a surface of the flange facing the other side of the filter medium.
摘要:
A compound selected from the group consisting of 4-quinolone and derivatives thereof, homoserine lactone derivatives, and indole and derivatives thereof, and salts thereof have an action of a microbial activity improvement agent, and when it is used for a microbial activity improvement method and a biological waste treatment method, the compound or the salt thereof is useful to achieve the improvement in the treatment capacity that transcends the limit of improvement in the treatment capacity of conventional biological waste treatment facilities.
摘要:
A radio resource allocation system in which equipment placed on a road allocates a radio resource to in-vehicle equipment that exists in a given area is provided. The radio resource allocation system includes the in-vehicle equipment mounted on a vehicle that communicates with another in-vehicle equipment by using the radio resource. The in-vehicle equipment includes a signal transmitting unit that transmits a signal showing that the own vehicle exists in the given area. The roadside equipment includes a radio resource allocation unit that allocates the radio resource to the in-vehicle equipment when the roadside equipment receives the signal transmitted by the signal transmitting unit, and a radio resource release unit that releases the radio resource when the roadside equipment does not receive the signal from the in-vehicle equipment that is allocated the radio resource by the radio resource allocation unit.
